potiuk opened a new pull request #19856:
URL: https://github.com/apache/airflow/pull/19856
We already have a mechanism to retry operations that could result
in temporary deadlocks - this have been helpful with handling MySQL
deadlocks - however similar problems occur occasionally in MSSQL and
there we get a DBAPIError rather than OperationalError:
`sqlalchemy.exc.DBAPIError: (pyodbc.Error) ('40001', '[40001]
[Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Transaction
(Process ID 55) was deadlocked on lock resources with another process
and has been chosen as the deadlock victim. Rerun the transaction.
(1205) (SQLExecDirectW)');
This PR adds DBAPIError to the list of errors that are handled
by `run_with_db_retries` to mitigate such occasional deadlocks.
